Multiple Select

Which of the following statements about tidal turbines are correct?

• Tidal turbines can be located anywhere there is strong tidal flow.

• Tidal turbines are lighter and cheaper than wind turbines.

• Tidal turbines are about 800 times stronger than wind turbines because water is denser than air.

• Tidal turbines capture more energy but are more expensive to build.

Open Ended

Explain how tidal barrages generate electricity and mention one environmental impact they may have.

Fill in the Blank

Hydropower relies on the ___ cycle to generate electricity.

Multiple Choice

Which of the following best describes the difference between a Run-of-the-River system and a Storage system in hydroelectricity?

• Run-of-the-River systems store water in reservoirs, while Storage systems do not.

• Storage systems use the force of flowing water, while Run-of-the-River systems use stored water.

• Run-of-the-River systems use the natural flow of the river, while Storage systems use water released from reservoirs.

• Both systems require water to be stored before generating electricity.

Fill in the Blank

The main ingredient of natural gas released from rotting garbage and agricultural waste is ___.

Multiple Choice

Which of the following statements best explains why geothermal energy is considered a renewable resource?
